Question

A field is in the shape of a right angled triangle whose base is 25 m and height 20 m. Find the cost of levelling the field at the rate of ₹ 45 per sq.m²

Answer 1

Area of a right angled triangle = `1/2 xx ("base" xx "height")  "unit"^2`

base = 25 m

height = 20 m

∴ Area = `1/2 xx (25 xx 20)`

Area = 250 m²

Cost of levelling per m² = ₹ 45

∴ Cost of levelling 250 m²

= 250 × 45

= ₹ 11,250

Cost of levelling = ₹ 11,250
